In comparison to a basis pursuit it significantly reduces the computational complexity, since the basis pursuit minimizes a global cost function over all bases present in the dictionary [47].
A representative of an American NGO noted that " There was a premise in the original formulation of the Global Fund that the US would pay a fair share of the global cost, and that is was based on some other equitable contribution assessments".
"The cost base of a global bank like ourselves is higher than it was before, because … it includes a significantly higher compliance and regulatory cost than historically the banks had invested in," said Gulliver.
"Interest rates are not a significant factor in our decision-making on investment because interest expense is only a small proportion of our cost base," says Ulf Quellmann, global head of Treasury at Rio Tinto, a mining group.
For example, SABIC, a petrochemicals company whose partial free float (70% of the shares are owned by the Saudi government) accounts for almost 30% of the stockmarket's value, is doing well on the back of a relatively low cost base and rising global demand for its products.A correction is likely eventually, but for now, with oil prices high, the good times continue.
The probabilistic approach is based on the Kalman filter for temporal tracking, whereas the global one is based on a global cost function.
To searching this regard, the cost-optimal methodology based on the global cost was defined providing a tool to assess different nearly-zero energy scenarios.
Based on the global cost efficiency, the global cost Malmquist productivity index was introduced to measure the productivity changes of the DMUs between two time periods when the prices of the inputs are at hand (Tohidi et al. 2012).
From the remark to Lemma 2 it follows that the second definition of α and its definition based on the global cost minimization are equivalent.
